Hi friend T4B !
is not a problem of Vesta or yours.
From an EXIM4 server and own or external DNS, it is not possible to avoid the SPAM tray of Outlook.com and Gmail.com
These giants have made it difficult!
Even if you have the perfect configuration of: SPF, DMARC, DKIM in your DNS and EXIM4.
It doesn't matter if SpamAssassin accepts your emails, the test web pages give you a good rating, but Outlook.com and Gmail.com will still reject you.
9,5 / 10 !!!
